guard: We, employ bolts. 18 which; extend! through.;the gnardlandibjaser. 10;" as presently described, and thus prevent the guard from sagging, but do not interfere with its free through insulating washers 21, and the bolts 1 each extend through a tube 22 which is held at its ends in the guard and in the base 10, being insulated from the base by a thim ble 22. The thimble 22" also carries a con tact plate 23 which extends along the base i in its outward position, but when the latter is moved inward by contact with an object, it moves against the tension otthe several springs 24; as well as against the tension of the bends 16. r

The guard 15 carries a series of generally U shaped contacts 25 which are supported 'on the tubes 22 which extend through their middle portion, and the free end portions 26 are preferably curved slightly so as to make an easy and resilient contact with the plate 23 when the guard is moved inward. This closes the circuit between the member 23 and the guard and terms a groundconnection. A plate 27 generally L shape is attached to the plate 23 and is insulated as shown at 28 from the bottom of the base 10 where it connects with a binding post 29. This can be connected with any conventional car control and signal apparatus so that when the guard 15 is moved inward itv will form a ground connection and the circuit will be closed from the binding post through the plate 23 and contacts 25.

In Figures 6 to 10 we have shown a structure which is like that already described except for some slight modifications of shape to better adapt the structure for use on the rear end of a car. As here illustrated the base 10 has its end portions curved and with the further exception that additional contacts 25 are provided. The means of supporting must be varied somewhat to adapt it to the ordinary rear construction of a car. Here instead of the bracket 11, the

bumper has inwardly curved arms 30 which have a sliding or adjustable connection 31 with the bracket 32 on the car. The arms 30- and bracket 32 connect by a sleeve 33,

and the overlapping parts are slotted as at 3A and fastened in the desired'position'by a bolt which extends through the slots.

Obviously the bumper might be supported in other ways it the car construction. required it in order to bring it into correct position at the rear of the car. i i From the foregoing description it will be seen that we have produced a strong, simple, resilient bumper which can be easily applied,

which serves its intended purpose well, and

is neat and compact in appearance.

We cla1m:-' a 1. A car bumper comprising a base bar,

a resilient bracket extending lengthwise ott-he bar attached thereto at the end portions and adaped for attachment to a car, and a guard member spaced apart-.froni'and extending generally parallel with thebase, the. end portions 01 the guard member being formed into loops extending around and spaced from the ends of the base, the terminals or the guard member being secured to the back of the base. 7

2. A bumper comprismg'a base bar member, means for supporting said memberon a car, a guard spaced from and extending generally parallel with the base, said guard being looped around and free of the ends of the base and attached to the base back, and

portions of the base and guard.

spring members arranged between the body 3. A car bumper comprising a base bar, a

guard spaced from and extending generally parallel withthe base, the guard? having bends at its end portions extending around 7 i and free of the ends of the base, the guard having its terminals attached to the back of the base, guide elements extending from the guard and sliding through the base, and spiral springs around the guide elements. I

4:. A car bumper comprising a base bar, a resilient bracket connected to the bar near its end portions and adapted for attachment to a car, a guard spaced apart from and generally parallel with the base, said guard being looped around the base ends "and attached to the back of thebase, a common fastening for the ends of thebracket and the terminals of the guard, and, springs disposed between the guard and base.

5. A car bumper comprising a base bar adapted to extend across the car end, means for supporting the base on a car, a guard spaced from and generally parallel withthe base, said guard being looped around and spaced from the base with its terminals '6. A car bumpercomprising a channel iron I base bar, m eans for supporting the base 7 bar on a car, a guard spaced from and generally parallel with the base, said guard being looped around the base ends out of contact therewith and with its terminals attached to the back of the base, spring members between the guard and'base, a contact plate on the base having conneotionwith a binding post, and contacts on the guard adapted to contact with the aforesaid plate when the guard is moved towards the base.

In testimony whereof, We have signed our names to this specification this 10th dayof October, 1927.
